MARSHALL HALL

At the same moment Dean is healed by Roy Le Grange, Marshall Hall is at a pool, attacked by a Reaper, and dies of a heart attack at exactly 4:17 p.m. The clock by the pool broke at that minute and hasn't worked since.

According to a man at the pool, Marshall "seemed healthy. Swam every day, didn’t smoke." He also saw Marshall freaking out, running, and saying that something was after him.

Quotes

Not that a man your age should be having heart trouble, but, still it’s strange it does happen.Dean: What do you mean, strange?Nurse: Well, just yesterday, a young guy like you, twenty-seven, athletic. Out of nowhere, heart attack.

Man: I’m telling you, he seemed healthy. Swam every day, didn’t smoke. So, a heart attack just kind of seemed, well, bizarre.Sam: And you said he was running, right before he collapsed?Man: Yeah, yeah, he was freaking out. He said that something was, uh, was after him.Sam: Did he say what?Man: Well, thin air is what. I mean, it wasn’t anything.Sam: Alright, thanks. (He starts to leave, but notices a stopped clock on the wall.) Hey, buddy? Your, uh, your clock’s busted.Man: Oh, yeah, we, uh, can’t get it workin’. Just froze at 4:17.Sam: Is that the same time Marshall died?Man: How’d you know?
